Proceedings Papers

Paper presented at the OTC Arctic Technology Conference, November 5–7, 2018
Paper Number: OTC-29109-MS
... Abstract During July 2018, an expedition was carried out offshore northern Newfoundland to central Labrador to profile, track, and forecast the drift of icebergs. One of the central goals of the drift modelling work was to test potential improvements in iceberg drift forecast accuracy up to 24...

Paper Number: OTC-29126-MS
... Abstract Offshore Newfoundland and Labrador, Canada, development costs associated with iceberg protection pose significant challenges in terms of project execution and economics for marginal field subsea tie-backs. The current standard practice is to assume that if an iceberg makes contact...

Paper presented at the OTC Arctic Technology Conference, November 5–7, 2018
Paper Number: OTC-29158-MS
... Abstract For oil and gas projects offshore Newfoundland, Canada, subsea structures are generally placed in excavated drill centres which lower the equipment below the natural mudline, protecting the equipment from damage due to iceberg impact. This paper introduces a concept of protecting...

Paper presented at the OTC Arctic Technology Conference, November 5–7, 2018
Paper Number: OTC-29096-MS
... Abstract Currently, iceberg risk mitigation at production facilities in shallower waters (80 to 120 m) on the Grand Banks off the coast of Newfoundland and Labrador is accomplished using iceberg surveillance, towing, water cannons and, in the case of floating facilities, disconnection. Future...

Paper presented at the OTC Arctic Technology Conference, November 5–7, 2018
Paper Number: OTC-29091-MS
... Abstract Icebergs can pose risks to platforms in arctic and subarctic regions. These risks require careful consideration during design, and as well during operations. Platforms must be designed to withstand potential impacts from icebergs, or to disconnect and move offsite to avoid impacts. ISO...

... Abstract Due to their potential instabilities, deploying personnel onto icebergs to make direct in-situ measurement is hazardous. The preliminary results from an investigation into the usage of Unmanned Aerial Vehicles (UAV) for surveying and monitoring icebergs are presented. The project had...

... Abstract The current practice for protecting wellheads and associated subsea facilities from icebergs on the Grand Banks is an Excavated Drill Centre (EDC), which is simply an excavation in the seabed in which wellheads and associated facilities are placed. Free-floating icebergs simply drift...
